Ambient temperature is usually the only factor used to regulate hog house ventilation systems. However, other factors such as humidity and air speed can also significantly impact the animals’ well-being. There can be a significant discrepancy between the animals’ actual needs and the performance of existing ventilation systems. That’s why it’s time we rethought and improved the environment-control strategies employed in the hog production industry.
This project proposes to measure relative humidity and air speed in hog houses and integrate these parameters into the control of ventilation systems. By doing this, we will be able to determine the temperature actually experienced by the animals and then adjust the ventilation system accordingly (by manipulating air flow and the air inlet opening) to ensure their comfort. Trial tests will be carried out in two IRDA breeding rooms in a fully controlled environment that replicates commercial hog house conditions.
From 2019 to 2021
The addition of certain parameters will make it possible to regulate hog house ventilation to better meet the needs of animals.

Cow-calf farms tend to prefer outdoor breeding, poor-quality drinking water can have a direct impact on animal health, and may lead to higher pathogen levels in the environment and at slaughter time, and negative consequences for food safety.
